Scanning extensible storage locations
The scan storage location feature allows you to manually update the statistical information for that storage location.
Statistics about extensible storage locations are maintained automatically by the DS-System. The values related to the Used size as well as the Used entries for extensible storage locations are accessible from the extensible storage locations dialog box.
In case the values displayed by DS-System are not accurate, DS-System administrators may trigger a scan process for an extensible storage location. The scan process will go through all the files from the DS-System online storage structure, to retrieve and update the statistics (note the amount of time this might take).
To scan a storage location:
1. On the Setup menu, click Storage, and then click Extensible Storage.
2. Select the extensible storage location you want to update and click Scan.
3. The Scan Storage dialog box appears. Configure the scan options:
• Additional scan threads – [For multi-threading] Choose the number of additional threads to use for the scan process.
• Require Storage Lock – Choose only if you require a 100% accurate scan result. The storage scan will only start if no other activity is using the storage, and it will only complete successfully if the scan is uninterrupted (because the storage scan process is the lowest priority activity on the DS-System).
NOTE: A scan process that is started without the storage lock option might provide a result that is not 100% accurate, since other activities might modify that same storage location. However, it will be able to complete (especially if the scan takes a long time) and provide a more accurate update of the statistics.
4. Click Start to begin the storage location scan process.
